' INVENTOR. WILL/AM 6f KELLER ATTORNEY 7 Patented Mar. 27, 1951 UNITED STATES PATENT OFFICE PERIODIC SIPHON METERING DEVICE FOR BOTTLES 6 Claims. 1

My invention relates to a liquid metering device for bottles and the objects of my invention are:

First, toprovide a liquid metering device for bottles, which automatically dispenses intermittently measured quantities of fluid from an inverted fluid container; 1

Second, to provide a liquid metering device for bottles of this class which may be used in connection with soft drink bottles or other bevera-e containing bottles for pouring the beverage into a plurality of glasses whereby the liquid containing bottle may be inverted and held in the inverted position during the pouring operating in filling a plurality of glasses, while the liquid is dispensed through said metering device in measured quantities intermittently, providing a time element intermediate each quantity-dispensation for movement of the metering device from one glass to the other;

Third, to provide a liquid metering device for bottles of this class which may be readily secured in connection with various conventional bottles;

Fourth, to provide a liquid metering device of this class which is very accurate in its measured dispensation of liquid;

Fifth, to provide a li uid metering device for bottles of this class which is particularly useful in dispensing measured quantities of various liquors; and

Sixth, to provide a liquid metering device of this class which is very simple and economical of construction, eflicient in operation, and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions, as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon, forming a part of this application in which:

Figure 1 is a longitudinally sectional view of my liquid metering device, showing by'dash lines a bottle in connection therewith; Fig. 2 is a side elevational view of my liquid metering device; and Fig. 3 is a fragmentary sectional view taken from the line 33 of Fig. 2.

Similar characters of reference refer to similar parts and'portions throughout the several views of the drawings.

The casing I and the gasket 2 constitute the principal parts and portions of my liquid metering device for bottles.

The casing I is provided with a neck portion la having a liquid outlet passage lb and an air inlet passage lc defined by an extending tubular portion ld, adapted to extend a considerable distance into the bottle A as shown by dash lines in Fig. l of the drawings. The casing l is provided with a substantially circular casing portion le in which the metering reservoir portion If is outlined by arcuate portions of the passages lb and lo. Communicating with the metering reservoir portion If and the fluid outlet passage lb is the port lg. Integral with the casing l is a pouring spout portion lh having a partition portion lk: terminating substantially on a level with the upper side of the dispensing reservoir portion If at its edge portion lm. The air inlet portion lc communicates with the passage portion I? of the pouring spout lh above the partition portion lie. The spout passage portion l7 communicates with the outlet passage lb at the upper edge lm of the partition portion lk. Communicating with the dispenser reservoir portion If and atmosphere externally of the casing l, is the port In, as shown best in Figs. 2 and 3 of the drawin s. It will be noted that the liquid dispensing reservoir portion If is substantially circular in form and that the air inlet passage portion I0 and liquid outlet passage portion Id are substantially arcvatelv dispos d about the liquid metering reservoir portion If providing a very compact liquid dispensing device. The pouring spout portion lh is disposed in substantially tangential relationship with the dispensing reservoir portion lf. Positioned around the neck portion la of the casing l is an annular gasket 2, which is preferably made of cork or other suitable material, adapted to fit the inner portion of a conventional bottle neck as shown by dash lines A in Fig. 1 of the drawings.

The operation of my liquid metering device for bottles is substantially as follows:

When the bottle A, as shown in Fig. 1 of the drawings, is inverted, liquid passes downwardly through the outlet passage portion lb, while air passes upwardly through the pouring spout passage portion ly' and air inlet passage portion lc- As the liquid passes downwardly through the passage portion lb, it transfers through the port lg, into the dispensing reservoir portion lf. As the liquid level rises in the reservoir portion If it reaches the level corresponding to the upper edge portion lm of the partition portion lk, whereupon the reservoir portion If is substantially filled and liquid starts to spill over the upper edge lm of the partition lie and passes downwardly through the passage l7 of the pouring spout lh. As the liquid reaches volume flow in the passage portion [7, the air passing through the air inlet passage I0 is shut ofi, causing a partial vacuum to be created in the bottle A, above the liquid level therein. As this partial vacuum builds to a certain value, the flow of liquid through the liquid outlet passage II) is stopped, and the liquid remaining in the dispensing reservoir portion If is siphoned over the upper edge 'lm of the partition 1k. After the remaining liquid has been siphoned through the passage M of the pouring spout ih, the liquid flow stops momentarily until suflicient air passes through the air inlet passage lc to relieve the partial vacuum in the bottle A, whereupon liquid again resumes flow through the liquid outlet passage lb and starts to refill the dispensing reservoirportion If. The intermittent time interval between liquid :u-pper portion internally of said reservoir, the

opposite end of said last-mentioned passage being on the opposite side of said reservoir from said neck portion and extending to an elevation f near the upper inner side of said reservoir, said dispensations is controlled by the rate of flow of the liquid in filling up the dispensing reservoir If ai-ter the partial vacuum in-the'bottle A has been relieved by resumption of airflow through the air inlet passage ,l c. It will be noted that during the filling operation of the dispensing reservoir portion if by liquid traveling downwardly through the liquid outlet passage lb, that air in the dispensing reservoir portion I f is relieved through the air relief port In, as shown best in Figs; 2 and 3 of the drawingspermitting the liquid level to rise readily in the liquid dispensing reservoir portion LI, and a so permitting the liquid to be siphoned readily therefrom through the passage 4-7 of theliquidpouringspout lh.

- Though I have shown and described aparticu- ;l;a rconstruction, combination and arrangement of parts and portions, I do not wish to be limited to the particular construction, combination, and arrangement, but desire to include in the scope of my invention, the construction, combination and arrangement substantially as set forth in the appended claims.
